How to make a character controller through another script

I am making a game with 9 character and using the move script it gets very repetitive, as i have to make a move script for each and every one of the nine characters. So instead what i intend to do is to make one move script on an empty game object and all of the characters (when active) can pass a speed value and jump value to the move script, and from there the script can move the character can move according to their speed/jump values.

I am testing out this feature on only one character before i add it to every character so i only have one character mentioned in the script

This is the move script :#

using UnityEngine;

using System.Collections;

public class Movement : MonoBehaviour{

 public Rigidbody2D Rigidbody2D;

 public void Motion (float speed, float jump){

     if (Input.GetKeyDown (KeyCode.W)) {

         Rigidbody2D.position = new Vector2 (Rigidbody2D.velocity.x, jump);
     }
     if (Input.GetKeyDown (KeyCode.A)) {
         
     }
     if (Input.GetKeyDown (KeyCode.D)) {
         
     }
 }

}

This is the Character Code :

using System.Collections;

public class scout_Move : MonoBehaviour{

 public static float Speed = 1.5f;

 public static float Jump = 5f;

 Movement Move = new Movement ();

 void Update () {

     Move.Motion(Speed, Jump);

 }

} Thank you so so so so much for the help this has been bugging me for 3 days now
